Be it known that I, iCLARENCE DnWlrfr LUIgnNs, :I citizen of the United States, re siding #been ofen Louie-See of Missouri, have invented certein newV end useful Improvements in Valves, of which, the following is e specification, reference being had therein to the 'accompanying drawings.

This invention reletes to valves, and has for its objlect to provide i; v Ive that is particularlyintended te be used to control the discharge 0f 'eetleue or other gas 'fram a reservoir whio lthe ges is stored or generated for .the pur ,05e Qf Supplyin the lamps .of an' aut n nol))ile, railway ooae locomo,tive,` etk:.' Another. objet@ 0f this inven'to iS @-0 prevde Locking means 'for the ppltingrerts o? thiewalv' .in Order to maintain e uplffm dlschigebf the gais' from ,the resrvmr and, alseiftevent the eperabing. arts from hlimg able means' 1n in o'penin in@ vreservoir ,2 is

Screw-threed" interna Y Iev the Screw-,threaded end .0f nek 3A ofthevlve Casing 4. Said neck is provided with a passage 5 which communicates with the interior. of 'reservoir 2 lund, also, with the velvef chamber 6 in said Casin A 'sciew-tlireaded plug 7 uc xloses one enl of chamber 6 and prSSeS 31. -PeCkillg, washer 8, firmly against the' lower.-eni 'of cesing 4 vin o 1 :der 'to prevent'the gafsflom escaping from said chember. The other end of chember '6 is tapered to form a Seat 9 for a valve 10 that is normelly held aga-inst Said sont by means of a 'spring 11.' Ar'projection 12 borne by said .valve extends into an epertureil?)v 1n plug 7 in order t0- guide said'valve in lits movement toward and ewa-y from seid sent. The stem 14 of valve 10 passes through opening 1 5 in casing v4 and projects into Vt e ,interior of a cup 16 i-n the u per end of saidcasing. A passage 17 exten s longitudinally 1n stem 14 and terminates in' a ertures 18 which pass transversely throug said stem., Said 90s@- 'by thelvfrring o the tutoapertures 18 communicate with chamber 19 within cesing 4, and, when valve 10 is moved from engegement with seat 9, the ges in .chamber (i4 passes into chamber 19` from cles casing 4. A sleeve '23 borne by member 20 extends inte.. .the interior 0f C11 16 and en oircles the Lipper end of valve-stem'lll. Seid sleeve presses. a. geskete in en annuler groove 25 in eup 1 6 in order to' prevent the ges from leaking 01st ef. Seid. cup, seidgeeket being formed off' lead or en other'seitble material A.

Sleeve 2 3 and abuts the upper end' 'of valve-Stern 1 4-,- and, when ste'ni 311:15

turned to move tovverd stem 14,-seid s 'lr'wm 14 pushes valve 1Q. evvey from sent 9 in brder'to allow the ges to ss from chamber 6 into Chamber 19i- A cap. 32 borne by mem bar.QO eucircles Stem 31. and presss e' packing-ring 33 egeinst pecking-34 Within stuifing-box 35 in said member in'order to pre- .vent the gasv from lenkngerounfd seid stem.

A portion of Stem 31 is screw-threeded to receive a lock-nut 36 that presses against cap 32 and holds stem 31 in any desirepo-- sitron to meintein a uniform ilow o the as from'chember 6 into Chamber-19.., A. lend-wheel 37 is fastened by means of rivets 38 or the like to flange 3 9 of stern 31 for the purpose of turninog seldstem. I A essgge 4 ext nds longitudinally througi stem 31' and registers with passage 17 in' stem 14. The up er portion of passage 40 is screw-threaded) t receive e screwthreeded 'portion of e ,valvestem 41. A valve 42 borne by stem 41 is 'movable towel-d and array from seat 43 in pssa-ge 40 in order to ..Moi the flow of gas through said raise-.ige 40. Apertmes l in stem'll coinmuah-.ate with pasfsage. 40 and vopen into chamber l5 within member A20. A pipe that is connected to member 20 communirate.;l with chamber 4.5 and conveys the gas, \\'heh enters said chamber, to u. pipe (not "hewn in the drawings) thatl leads it() the lamps ot the aatomoiile.` When stem 41 is turned no that valve 42 moves a way from -cat Vlil, the gas that. enters paesage 40 from l passage 1T Hows tlm-engl! apertures 44 into f chamber l5 from which it passes through. pipe {H l.

cap flT borne by the upper end of Stem :ll enen-cles: lem il and causes packing ring 1S to ness packing' 4:9 inte stnliing-box 5() i in said sten: 3l in order ,1.0 prevent the gas from leaking out of passage 10. Stem ill is provided iiith a loeirrait- 5l by means ol which said Stem is locked from being related in ordm: to maintain a uniform flow of the gars thrtmgh :ipc-tintes ile. A hand- .v'hr:e'i 5i; herne. by the alzi-.cr end of stein -ll all'ords: a nit-ans tar turning saine.

'the operation of the. valve is as follows.: 'When hand-wheel 37 turned in the direetion to canse stem .-ll to move toward stem ld, said stem Ill cantes stein 111 to push valve l() away from seal'. i), whereby thc gus in 'chamber (3 paese-. inte chamber 1D and then Hows through aiazrtnres 1S into passagev 1T, Alter the. valve 10 is moved away frffan seat E) the stern 3l is locked by means ol' leek-nut 36. Hand-wheel 59, is then turned to canse stem 4l to draw valve -12 away from' reet. 43, 4whereby the gas that enters panseg'e 40 from passage 17 passes through apertures 44. into chamber 4:5 from which it. asses through pipe 4G. Loek-nut 'l is then tightened-to prevent stem lililrom being rotated and to maintain a uniform' flow of the gas through .pipe 4,6.

ln order to cut uit the flow of gas thronf'hpipe Ll(,eithm= the.lmnd\\hee1 52 een' turned te eaase valve 42 to engage sont 13,
